"It turns out that the knife used by the Lu family is made of Xuanbing black iron. Jiang Ning muttered to himself in his heart, and he already had a rough process in his mind for the Lu family to forge weapons.

Because the weapon made of Xuanbing black iron is extremely hard, it can't be easily broken with Jiang Ning's current strength, but Jiang Ning easily destroyed the Lu family's knife into slag before, which shows that the material used to build the knife is not pure Xuanbing black iron at all, and it must be mixed with impurities.

"I'll have to figure out where to put the black iron they have refined. ”

A treacherous smile appeared at the corner of Jiang Ning's mouth, the Lu family has been mining in this mine for so many years, there must be a lot of inventory, if they can loot this Xuanbing Black Iron, then they will make a lot of money.

Xuanbing black iron is the material for casting spiritual treasures, although it is not superior, but it is much better than the hundred-year-old Xuantian iron that Jiang Ning accidentally obtained before, and even if it is not used to cast spiritual treasures, just absorbing the spiritual energy in Xuanbing black iron is also a very good choice in this earth where spiritual energy is scarce.

"What are you laughing at?" Suddenly, Lao Zhang looked at Jiang Ning and asked.

"I didn't ...... It's nothing. Jiang Ning hurriedly shook his head and immediately returned to the way he was.

"Inexplicable. Lao Zhang said, picked up the hoe from the side, and threw it to Jiang Ning: "Hurry up and get up and work, there are still 10 days left in this month, I think you are a novice, so I set your goal a little lower, and by the end of the month, you must dig out 20 pieces of ore of this size." ”

Jiang Ning has now reached his first goal, now that he is in the mine, it is easy to get rid of this mine and escape, but if he wants to get the Xuanbing Black Iron, it will take a while of effort, but now the situation on the Lin family's side is still unclear, he can't stay here for long.

Jiang Ning focused on Lao Zhang, who had worked here for a long time and was definitely very familiar with this place, and if he could find a breakthrough from Lao Zhang, he would definitely be able to greatly shorten the time required.

In the next few days, while Jiang Ning was working, in the name of asking for advice, he asked Lao Zhang side by side, and secretly inquired about the situation on the other hand.

However, Lao Zhang's mouth was very strict, and Jiang Ning barely asked any useful information from his mouth, but after a few days of investigation, Jiang Ning had completely figured out the patrol area and shift time of the guards in the mine, which laid favorable conditions for his future actions.

Not only that, Jiang Ning has also discovered a strange phenomenon in the past few days, that is, when all the miners leave the mining area, a few people in black clothes will come in, and these people are all martial artists, Jiang Ning senses that the strongest of them is infinitely close to the acquired realm.

Although this mineral asset is quite precious, the Lu family has done a good job of secrecy, and there are very few people who know the entrance to the mine, otherwise Jiang Ning would not have bothered to be beaten by Lu Quan and let him arrest him.

Since in this case, how can there be so many masters, and each time they go in and stay for about half an hour, and then leave, Jiang Ning thinks about what secrets are hidden in it?

With this question in mind, Jiang Ning came to Lao Zhang's side when he was eating.

"Brother Zhang, who are these people, what are they doing when they go in for half an hour every day?" Jiang Ning pretended to be curious and asked Lao Zhang.

"Why are you asking so much about your meal?" Lao Zhang still refused to tell Jiang Ning anything, and glared at him.

"I'm just curious to ask, and I feel that the person who takes the lead is very strong, it is impossible for this kind of person to come to mine, right?" Jiang Ning shrugged his shoulders, and then continued to say sideways.

"Nonsense, of course not to mine. Lao Zhang glanced at him, and then said: "Alas, it's okay, don't ask, it's the third day, how many mines have been dug up?"

"Hehe, it's not much, it's already 8 yuan. Jiang Ning pretended to be embarrassed, touched his head and said.

"Okay, Xiaochuan, I see that you have a good physique, and you used to be a practitioner?"

Lao Zhang was also a little surprised when he heard this, after all, it would take two days for the people who had just been arrested to recover their physical strength and accept this fact, and Jiang Ning was not only able to work on the same day, but also better than the old people who had been working here for several years.

"It's okay, I used to keep working out every day, my physical fitness was a little better, and I also learned a little bit of body skills. Jiang Ning replied.

"I see. ”

Lao Zhang nodded, and he understood Jiang Ning's curiosity.

"Don't think about other things, you can work with peace of mind, there have been people with very strong fists and kicks who have been caught in the past, and they resisted several times and wanted to escape, and in the end the end was miserable. Lao Zhang advised Jiang Ning, and then continued to eat.

That night, Jiang Ning rested in the tent in the mine as usual, he pinched the time to wait for the gap between the guards to change shifts and sneaked in to investigate the situation, but suddenly sensed a slight movement outside, Jiang Ning quickly got up, quietly lifted the tent curtain, and saw a figure, sneakily walking out.

Seeing this, Jiang Ning quietly followed, and found that this figure turned out to be Lao Zhang, although the terrain in the mine was complicated, but there was only one exit, and at this time Lao Zhang was moving slowly towards the exit.

"This old Zhang persuaded me not to think about running away during the day, why is he running away now?"

Jiang Ning was puzzled, but he didn't show up, and still followed silently.

Lao Zhang continued to walk towards the entrance of the cave, but turned a corner at the fork in the road that was about to approach the entrance of the cave, but he remembered that turning into it was a dead end.

Jiang Ning, who couldn't figure out the situation, even if he chose to continue to follow, but after all, there was only one way, so he would definitely be discovered by Lao Zhang.

Sure enough, after reaching the bottom of the dead end, I saw Lao Zhang standing on tiptoe, pounding something on the top of the cave with both hands, as if he was holding something to the small hole at the top, and after finishing the work, he squatted down and picked up a stone to block the hole dug out.

"Brother Zhang, what are you doing here?" In the quiet environment, Jiang Ning's voice was particularly obvious, and Lao Zhang was startled when he heard it, only to see him trembling all over, and he fell to the ground in fright.

"Xiaochuan, you're scared me to death!" Lao Zhang gasped heavily when he saw that it was Jiang Ning.

"Brother Zhang, what are you doing here in the middle of the night? I think it's so familiar with the things you took just now, isn't it the ore in our mine?"

Jiang Ning looked at Lao Zhang and found that he had a nervous look on his face, obviously being said by Jiang Ning.

"Brother Zhang, didn't you tell me before that there are rules in the mine that you can't hide ore privately? It seems that you have caught someone who is going to be chopped up, right? Why did you do this?"
